Also, software is provided for a number of demonstrations that illustrate the advanced capabilities of the dE2-70 board In order to use the de2-70 board, the user has to be familiar with the Quartus II software. The necessary knowledge can be acquired by reading the tutorials Getting Started with Altera 's dE2-70 Board and quartus lI Introduction(which exists in three versions based on the design entry method used, namely Verilog, VHDL or schematic entry ). These tutorials are provided in the directory DE2 70 tutorials on the DE2-70 System CD-ROM that accompanies the DE2-70 board and can also be found on Altera's DE2-70 web pages 2.2 Block Diagram of the DE2-70 Board Figure 2.2 gives the block diagram of the DE2-70 board. To provide maximum flexibility for the user,all connections are made through the Cyclone Il FPGa device. Thus, the user can configure the fPga to implement any system design ADBRA DE2-70 User Manual 50Mhz/28 Mhz/Ext In USB 2.0 Host/Device Kh 24-bit Audio CODEc 10/100 Ethernet PHY/MAcKH XSGA 10-bit Video dac SD Card TV Decoder(2) Cyclone ll IrDA Transceiver FPGA User Green LEDs (9) Flash(8 Mbyte) 2C70 User Red LEDs (18) SDRAM (64 Mbyte 16X2 LCD Module SRAM (2 Mbyte PS2 &RS-232 Ports 7-SEG Display (8) DPDT Switches(18) Expansion Headers(2) Push-Button Switches(4) EPCS16 USB Config Blaster Dev Figure 2. 2.
